Patients were given an intravitreal injection of antibiotics (vancomycin-amikacin) and steroids (dexamethasone), systemic antibiotics (pefloxacin-piperracillin), and systemic steroids in bolus.

TPA-assisted vitrectomy for proliferative diabetic retinopathy: results of a double-masked, multicenter trial.

Objective: Some complications of vitrectomy are related to adherence of the vitreous body to the retina. We studied whether these complications could be decreased by injecting a proteolytic enzyme, tissue plasminogen activator (TPA), at the beginning of surgery to aid separation of the vitreous from the retina.

Methods: Fifty-six patients receiving surgery for complications of proliferative diabetic retinopathy were divided into two groups in this prospective, randomized, double-blind study.

Material And Methods: We have studied 21 eyes implanted with an anterior chamber phakic IOL between May 1989 and June 1990. The 21 eyes had a very high myopia (mean pre-operative myopia--13.

Surgically induced astigmatism with superior and temporal incisions in cases of with-the-rule preoperative astigmatism.

Purpose: To evaluate surgically induced astigmatism (SIA), postoperative astigmatism, and uncorrected visual acuity (UCVA) after cataract surgery with superior corneal, superior scleral, and temporal corneal 4.0 mm sutureless incisions in cases of preoperative with-the-rule (WTR) astigmatism.

Setting: Hopital des Quinze-Vingts, Paris, France.

[Macular imaging with optical coherence tomography].

Purpose: Optical Coherence Tomography (OCT) is a novel noninvasive and noncontact imaging technique providing cross-sectional representations of the eye structures. OCT is analogous to Ultrasound B-scan, except that it analyzes the reflection of a 850 nm light wave. The aim of this study was to assess the potential of ocular coherence tomography for diagnosing and monitoring macular diseases.

Aim: To evaluate sub-Tenon's anaesthesia as an alternative to peribulbar anaesthesia.

Methods: 109 consecutive patients listed for various eye operations (including cataract, trabeculectomy, and vitrectomy) under peribulbar anaesthesia were operated on under sub-Tenon's anaesthesia instead. After topical anaesthesia a buttonhole was fashioned through the conjunctiva and Tenon's capsule 10 mm posterior to the limbus.
